IMPROVEMENT IN APPARATUS FOR DRAWING WATER FROM WELLS.

Specification forming part of Letters Patent No. 9,702, dated May 3, 1853.

To all whom it may concern:

Be it known that I, SAMUEL R. WILMoT, of New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements on the Apparatus for Raising and Conveying ater; andI do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which the several parts are represented as follows:

Figure 1 is a side elevation of the apparatus. Fig. 2 is a side elevation of the elliptical spring, pulleys, and bucketsuspension rod. Fig. 3 is a front elevation of the same. Fig. t is a vertical section through the axis of the post C and arm B, showing the fastening of the wire A. Fig. 5 is a front elevation of the car 0 on the rear of the car.

Similar letters refer to corresponding parts in the several figures.

The object of the apparatus upon which my improvements are made is to afford the means of drawing and conveying water from springs by means of a bucket suspended from a car running upon a curved wire track, the car and bucket being operated by means of a cord fastened at one end to the carand held atthe other by the operator.

My invention consists in combining with an elliptical spring, having at each extremity of its conjugate axis a grooved wheel, the prolongation of the suspending-rod forming the axis of the upper, a stud projecting from said suspending-rod causing the rod to act as a lever to draw together the grooved wheels, so as to embrace closely the way between them and steady the motion of the bucket, the fulcrum of the lever being the contact of the stud and inside of the spring, this stud acting, also, to prevent the bucket from swinging in front of the way when descending into a well, and from revolving around its point of suspension when at the bottom, and, further, to limit its oscillations when the car is moving on the way.

In the drawings, Ais the curved track composed of stout iron wire fastened to the extremities of the arms B B of the posts C C by the straps of sheet-iron b, which inclose the wire A, and are inserted into the cuts a in the arms 13 B, where they are held firmly by the screws 0, passing through the arms and the ends of the straps. These straps inclose the wire so closely as to form but a small projection and oifer no obstruction to the movement of the pulleys. The number of posts used would of course depend upon the distance which the water had to be conveyed. The track is curved, as is seen at d, permitting its extremity to descend into a well, and is bent, as seen at g, which angle, in connection with the peculiar construction of the car, prevents the bucket from slipping 011 after it has completed its descent.

The car by which the bucket is operated consists of an elliptical spring 0, at the extremities of the conjugate axis of which are projections, through holes in which pass the j ournals of the pulleys ff. Of these pulleys the former is above the track and the latter below it, the wire being inclosed by the grooves in the faces of the pulleys. Attached to the spring 6 is the arm m, having at its extremity the ear 0, passing over the wire A, for the purpose of steadying the car and keeping it upright. To the extremity of this arm on is attached the cord by which the apparatus is operated.

It is easily seen that a car constructed as above described is free to move from one extremity of the wire track to the other. The

bucket is connected by the following arrangement:

The journal of the pulley f, after passing through the eye at in the upper part of the spring '6, is bent down, forming the rod 7c,which is fastened securely to the upper part of the handle of the bucket, thus making the point of suspension of the bucket in the axis of the upper pulley f,which rests upon the Wire track. Upon the rod is is the arm p, which, by press ing against the inside of the spring 6, as shown in Fig. 2, causes the wheels to closely embrace the wire track and steady the apparatus, the rod 70 acting as a lever, having its fulcrum at the point of contact of the arm 19 and spring e. This arm 19 also prevents the bucket from swinging in front of the wire track. Projecting from the post nearest the well is the arm X, on which is a roller X, upon which the cord P rests when the bucket is in the well, and which serves as a pulley in drawing it up until the bucket has passed the curve d of the track A, when it is no longer required.

The mode of operating this apparatus is as follows: The bucket being at the upper extremity of the track, if the cord P be loosened, t will descend to the bottom of the well by its own gravity and fill itself. The car cannot run off the track, as the lower face of the pulleyf, the upper face of the pulley f, together with the car 0 at the extremity of the arm m, embrace the wire so closely as to prevent the car from turning the angle 9 on the lower end of the track A. The bucket is raised by the operator drawing the cord P, the arran gement of the two pulleys allowing the car to travel up the almost vertical wire track in the well. After the bucket has surmounted the curve 01 it is drawn by means of the same cord to the upper extremity of the track A. During the operation and while the bucket is at the lower portion of the way the stud p presses against the inside of the spring 6, as shown in Fig. 2, causing the pulley f, to which the rod 70 is attached, to press upon the upper surface of the way, while the lower pulley f is drawn close to the under side because of the nature of the spring e, which must draw in thedirection of the pressure of the stud 19, thus causing the pulleys f and f to closely embrace the way and steady the movement of the apparatus. The stud p, by being limited in its movements by the sides of the spring 6,

prevents the bucket from swinging in front of the way and overturning the car, or from oscillating too much with the same bad effect. In fact, this stud may be considered as the general regulator of the apparatus, without which its operation would be imperfect and limited.

What I claim as my invention, and desire to secure by Letters Patent, is

The projecting stud p, in combination with the spring 6 and grooved pulleys ff, for the purpose of contracting the spring 6 by the Weight of the bucket and causing the pulleys to grasp firmly the way, in the manner and for the purposes herein specified.

In testimony whereof I have hereunto subscribed my name before two subscribing witnesses.

S. R. VILMOT.
